@0:33 they say something. The first mountain cog railway was the Mount Washington Cog Railway in the U.S. state of New Hampshire, which carried its first fare-paying passengers in 1868. The track was completed to reach the summit of Mount Washington in 1869.
@micahthatrocks well they brought the #4 out last weekend for a test run so you may see steam going at least part way "no water tanks remain to refill locos aside from the one at the bottom" up the mountain some time soon.
Not only did they forget Mt Washington, they also forgot Snowdon in Wales and I believe there was a rack railway in coastal California at one time; there is also at least one historic rack railway in Greece.
Major point-source of pollution with that little kettle burning bituminous coal without secondary air. At least they could have tried anthracite. What TYPE of rack, back then?
